Predictors of excellent functional outcome in aneurysmal subarachnoid hemorrhage.
Case fatality rates after aneurysmal subarachnoid hemorrhage (aSAH) have decreased over time, and many patients treated with modern paradigms return to a normal life. However, there is little information on predictors of excellent functional outcome after aSAH. In this study, the authors investigated predictors of excellent outcome in a modern consecutive series of patients with aSAH. ⋯ Excellent outcomes (mRS score 0-1) can be achieved in the majority of patients with aSAH. The likelihood of excellent outcome is predicted by good clinical condition after resuscitation, absence of ICH on presentation, no evidence of infarction on brain imaging, and absence of blood transfusion during hospitalization.

Comparative StudyQuality of life following surgery for large and giant vestibular schwannomas: a prospective study.
Prospective studies of quality of life (QOL) are infrequently performed in patients undergoing surgery for vestibular schwannoma (VS). The authors designed this to study to investigate health-related QOL (HR-QOL) in patients with large and giant VSs before and after surgery. ⋯ Patients harboring large or giant VSs score lower on all the QOL domains compared with the normative population. More than 60% showed a clinically significant improvement in HR-QOL 1 year after surgery, a result that was sustained at subsequent follow-up.

Impact of early-onset seizures on grading and outcome in patients with subarachnoid hemorrhage.
After subarachnoid hemorrhage (SAH), seizure occurs in up to 26% of patients. The impact of seizure on outcome has been studied, yet its impact on grading is unknown. The authors evaluated the impact of early-onset seizures (EOS) on grading of spontaneous SAH and on outcome. ⋯ Patients with EOS were classified significantly more often in a poor grade initially, but then they significantly more often achieved a good outcome. The authors conclude that EOS can negatively influence grading. This might influence decision making for the care of patients with SAH, so grading of patients with EOS should be interpreted with caution.

Case ReportsConflicting pathology reports: a diagnostic dilemma.
The differential diagnosis of a brain lesion with two discordant pathology reports includes the presence of collision tumor, metaplastic changes, and labeling errors that occurred during the processing of the specimen. The authors present a case in which the first brain biopsy from a 47-year-old patient with a history of heavy smoking was compatible with metastatic small cell carcinoma, and the second biopsy taken during decompression craniotomy 3 weeks later was compatible with WHO Grade IV glioblastoma. Using short tandem repeat (STR) analysis of the two specimens and nontumor-derived patient DNA, the authors found that the two specimens did not belong to the same individual. The authors conclude that allele imbalance or loss of heterozygosity detected by STR analysis is a reliable and valuable diagnostic tool for clarifying discrepancies in discordant pathology reports.

Comparative StudyComparative effectiveness of antibiotic-impregnated shunt catheters in the treatment of adult and pediatric hydrocephalus: analysis of 12,589 consecutive cases from 287 US hospital systems.
The real-world effectiveness of antibiotic-impregnated shunt catheters to reduce the incidence of shunt infections is still debated. The literature to date consists mostly of small, single-institution studies. The aim of this study was to assess the incidence of infection for antibiotic-impregnated catheters (AICs) versus standard shunt catheters in a large nationwide administrative database. ⋯ The use of antibiotic-impregnated shunt catheters was associated with a reduction in shunt infections for both adult and pediatric patients. This provides further support that AICs may represent a reliable means of reducing shunt infections for both adult and pediatric patients.
